What is the difference between organic fertilizer and compound fertilizer?
Organic fertilizer granulator includes disc granulator machine, drum granulator and new organic fertilizer granulator. Compound fertilizer granulator includes disc granulator, drum granulator and double roller granulator(npk fertilizer granulator). You may have discovered that both disc granulators and rotary granulators can produce organic and compound granulated fertilizers. Making organic fertilizer, composting is the key process. In order to make your composting complete quickly, Huaqiang has manufactured a variety of composters with different composting methods. For example, there are crawler organic compost turners and small turners to meet your composting requirements. What's more, if you want to use the trench composting method, we also have trench compost turners, large wheel compost turners and chain plate compost machines to make biological compost for you. The preparation of compound fertilizer granules is slightly different from organic fertilizer. The raw material for making granular compound fertilizer should be in powder form. And what you need to do is crush different kinds of pure fertilizer into powder, and then make ingredients according to requirements. In order to get a better granulation effect, you can equip a powder mixer to mix them evenly. Generally speaking, a double roller granulator can be used to make dry compound granular fertilizer. Among all the fertilizer granulators of Huaqiang Heavy Industry, only the twin-roller granulator adopts dry granulation technology. In addition to compound fertilizers, other granules can also be produced using a twin-roller granulator, as long as the moisture content is between 5% and 10%. The granulation rate of the twin-roller granulator is above 93%. Huaqiang wet fertilizer granulator includes disc granulator machine, drum granulation and new organic fertilizer granulator. These granulators require the moisture content of the raw material to be between 25% and 30%.
Which method of manufacture is the least expensive for prescription drugs?
Dry granulation processes create granules by light compaction of the powder blend under low pressures. The compacts so-formed are broken up gently to produce granules (agglomerates). This process is often used when the product to be granulated is sensitive to moisture and heat. Dry granulation can be conducted on a tablet press using slugging tooling or on a roll press called a roller compactor. Dry granulation equipment offers a wide range of pressures to attain proper densification and granule formation. Dry granulation is simpler than wet granulation, therefore the cost is reduced. However, dry granulation often produces a higher percentage of fine granules, which can compromise the quality or create yield problems for the tablet. Dry granulation requires drugs or excipients with cohesive properties, and a 'dry binder' may need to be added to the formulation to facilitate the formation of granules.
What is a gold working technique where minute granules are fused in a pattern to a larger surface?
The technique you are referring to is called granulation. It involves attaching small granules of gold to a surface using heat without melting the granules completely. This process results in intricate designs and patterns on the larger piece of gold.
What is the difference between wet granulation and dry granulation?
The dry granulation process is used to form granules without using a liquid solution because the product to be granulated may be sensitive to moisture and heatWet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid (the process of adding a liquid solution to powders). The fluid contains a solvent which must be volatile so that it can be removed by drying, and be non-toxic
How to solve the wall sticking problem of drum granulator?
Huaqiang plant chemical fertilizer equipment rotary drum granulator solves the problem of wall sticking. Fertilizer drum steam granulation production process has greater output flexibility. The drum granulator is cylindrical and has good heat preservation effect. Using steam to increase the temperature of the material during granulation to meet the liquid phase required for granulation can greatly reduce the water content of the material during granulation, reduce the load of the dryer, and increase the output of the whole machine. The granulation method of the rotary drum granulator, the double roller granulator adopts dry granulation, and the main working method of the drum granulator is wet granulation. After the base fertilizer is humidified by a certain amount of water or steam or gaseous ammonia or phosphoric acid or nitrogen solution in the cylinder, the compound fertilizer granulation process for chemical reaction and heat supply or the cold granulation process for a small amount of compound fertilizer adds water. Under the condition of temperature and humidity, with the help of the rotating motion of the cylinder, the material particles are squeezed and agglomerated into balls. The improvement of the drum granulator, the drum granulator has a wide range of adaptability to raw material production. It can be used in conjunction with low-solubility and high-solubility materials as required, and can also be used in conjunction with some organic matter and medium and trace elements. In the process of organic fertilizer manufacturing, the wall sticking problem of the drum granulator is relatively serious, which directly affects the movement of materials, affects the ball forming rate and the roundness of particles. In order to solve this problem, we have developed a high lining for the inner wall of the granulator. The active lining of molecular materials solves the problem of material sticking to the wall and plays the role of anti-corrosion and heat preservation. The drum granulator is suitable for nitrogen, phosphorus and potassium nutrients, and the ratio of nutrient distribution is flexible. It can process high-nitrogen compound fertilizers, various special fertilizers, organic and inorganic compound fertilizers containing more than 20% nitrogen, and can be used in both npk production line and organic fertilizer production lines.
How do fertilizer plants prepare Granular Urea?
Taking a 50000 tons urea fertilizer plant as an example, the process of making granular urea fertilizer as follows: materials batching, raw materials mixing, materials crushing, granulation by pan granulator, urea granules drying, cooling, granular urea screening, packaging etc. the whole process includes at least eight fertilizer machines to work together. Of course, your fertilizer yearly yield depends on the number of fertilizer machines. At the same, you should consider the raw materials of urea fertilizer and urea shape. This is a video shows the whole process of making fertilizer in fertilizer plant.
What are the disadvantages of wet granulation?
As wet granulation requires multiple steps for extra blending, granulation, and drying, it can be time-consuming. Wet granulation is also unsuitable for water sensitive active pharmaceutical ingredients due to their incompatibilities with water. As the granule are dried in elevated temperatures, the high temperatures may lead to instability. Failure to accurately determine the endpoint of the wet granulation process may also lead to compaction and dissolution problems. The material may also stick to the walls of the machine during the process instead of being added to the granules.
What compound used in fertilizer manufacturing is produced by the haber process?
ammonia
What is granulation on the sun caused by?
The grainieness is caused by convective cells at the sun's sufrace. Hooter material rises up at the centers of these "grains" (called granules) while less hot material sinks around their edges. Each granule is several hundred miles across.
What is wet granulation used for in the pharmaceutical industry?
Wet granulation is used to improve the flowability of the particles, increase the uniformity of the contents of the drug, unify the size of the particles, reduce the segregation of different components of the drug, and to increase the density of the material. Due to the advantages of wet granulation, it is the most common granulation method in the pharmaceutical industry.
How to use animal manure to produce manure organic fertilizer?
Generally speaking, if you want to obtain organic fertilizer, it is best to use organic fertilizer production equipment. This is the machinery needed to produce organic fertilizers. Manure solid-liquid separator. If you have animal manure raw material or some other organic fertilizer raw material. You'll find a lot of moisture in it. Therefore, you need to use a machine to deal with the moisture of the raw material. By using the manure solid-liquid separator, the moisture in the manure raw material will be reduced to 30%-40%. Compost Turner. There are a lot of harmful bacteria and microorganisms in the fecal material. You should use a waste disposal machine to kill these bacteria. A manure composter can help with that. Feces Crusher. After the composting process, you will find lumps of manure. To solve this problem, manure shredders turn lumpy manure into powdered manure. Feces organic fertilizer granulator machine. If you want to obtain more efficient organic fertilizer, you can use an organic fertilizer granulator to make granular fertilizer. In the granular fertilizer production line, there must be powdered fertilizer first. Powdered fertilizer can be put into fertilizer granulator to make fertilizer granules. Honestly, there are two methods of granulation, wet granulation and dry granulation. If wet granulation is used, a drum dryer and drum cooler are required to remove moisture from the manure pellets. Common organic fertilizer granulators include: npk fertilizer granulator, transfer granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, each granulator has its own production characteristics, and the fertilizer granulator machine price varies. Automatic packing scale. In order to save time in fertilizer production, automatic packing scales can be used to pack manure fertilizers.
What is the working principle of the organic fertilizer production line?
When it comes to organic fertilizer, the first thing that comes to mind is fermented pure chicken manure and sheep manure. In fact, now the machinery is specialized in processing livestock and poultry manure into organic fertilizer granules for sale. In this process, an organic fertilizer production line is needed, so what is its working principle? The processing of organic fertilizer is mainly the collection of raw materials, and then the raw materials are proportioned according to the required formula, the moisture content of the raw materials, the carbon-nitrogen ratio of the raw materials are adjusted, and fermentation begins. Fermentation turning machine: Turn the raw materials during the auxiliary fermentation process, provide sufficient oxygen for the raw materials, control the temperature, and make the raw materials ferment more evenly and fully. Crusher: The size of the fermented materials is not uniform, and the semi-wet material crusher can be used to finely crush them. Granulator: The crushed materials are made into organic fertilizer granules of uniform size through the organic fertilizer granulator. Drying and cooling machine: The granulated organic fertilizer still contains about 30% moisture. In order to increase its strength, the granules need to be dried and cooled. It is also more conducive to later storage and transportation. Drum screening machine: After granulation, there will be a small amount of unqualified particles, some of which are too large and some are too small. Use a screening machine to screen them out, and the oversized particles will return to the crusher, and the undersized particles will return to the granulator for re-granulation. The qualified particles will flow into the automatic packaging machine. Packaging machine: After the finished organic fertilizer particles are packaged by the automatic packaging machine, the processing flow of the entire organic fertilizer production line is completed. It should be noted that the above configuration is a conventional organic fertilizer production line configuration. In the actual production process, there will be slight adjustments due to different formulas and production processes.
